| Summary: | 碩士 === 國立成功大學 === 水利及海洋工程學系專班 === 91 === In this paper, a method was developed to establish
both velocity profile and concentration profile for
uspended sediment based on the measured data of
average velocity and average suspended sediment
concentration. In addition, a numerical model for
computing suspended load and bed load was also
developed for computing bed load transport rate when
measurable load is available. In the study, bed loads
for published laboratory and field sediment data were
computed using the presently developed numerical model
based on four different bed layer thickness. The
computed bed loads were found to be in reasonable
agreement with the values from Einstein’s bed load
function when the thickness of the bed layer was taken
at 10θd or 0.05D. The numerical model developed in the
present study may be used to evaluate the validities of
other bed load formulas.
